On the numerical solution of Lasserre relaxations of unconstrained binary quadratic optimization problem [PDF]

open access: yesJournal of Global Optimization
Abstract The aim of this paper is to solve linear semidefinite programs arising from higher-order Lasserre relaxations of unconstrained binary quadratic optimization problems. For this we use an interior point method with a preconditioned conjugate gradient method solving the linear systems.

Variable Reduction For Quadratic Unconstrained Binary Optimization

open access: yesCoRR, 2021
Quadratic Unconstrained Binary Optimization models are useful for solving a diverse range of optimization problems. Constraints can be added by incorporating quadratic penalty terms into the objective, often with the introduction of slack variables needed for conversion of inequalities. This transformation can lead to a significant increase in the size
